Hyperspectral Cube
Definition
Spatial data with a spectral dimension defined by the instrument and measurement mode. A hyperspectral dataset links spatial positions with spectral measurements. Wavelength range, illumination, detector response and measurement mode define its information.
- Context
- Spectral imaging
For example, two spatial regions can have different recorded spectra without that difference alone establishing which substance each contains.
A spectral difference does not automatically identify a substance or source. Calibration, sampling and a validated interpretive method are needed.
